The challenge might take geocachers months or even years. Because of its comparatively small size, The Rhode Island DeLorme Challenge can be completed by a well-prepared geocacher in a single day. The challenge, called “Little Rhody DeLorme Challenge” (GCZK7D), was created by BBWolf+3Pigs in November of 2006. So far, more than one hundred geocachers have logged a smiley on “Little Rhody DeLorme Challenge.”
